I just made up that name. For my whole life it has just been "mom's fudge". Such a forgettable name. But Five Three? Better right? Maybe when you understand what the five and three stand for. Five minutes. Three ingredients. I'm serious. And it's good. You might be able to find comparable fudge out there, but chances are it requires fancy equipment, lots of time, and a super attentive cook. Not Five Three fudge. This is the perfect last minute Christmas treat. At our house, it isn't Christmas without the fudge.
